MOLD.

Specification of Letters Patent. Patented June 23, 1914.

Application filed February 21, 1914. Serial No. 820,200.

To'aZZ whom it may concern.'

Be it known that I, GEORGE P. KLINE, a'

citizen of the United States, residing at IVilkes-Barre, in the countyof Luzerne and State of Pennsylvania, have invented certain new anduseful Improvements in Molds; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to molds provided with cleaning gates and used inmetal founding; and it consists in the novel construction andcombination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a vertical section through a mold providedwith a cleaning gate and strainers according to this invention. Fig, 2is a side view, and Fig. 3 is a plan view, of the upper disk. Fig. 4 isa side View, and Fig. 5 is a plan view of the lower disk.

The mold or metal space 2 is formed in the sand 3 contained in the lowerboX 4, and a core 5 is shown in the mold. The top boX 6 has a riser 7,and a pouring gate 8 formed in the sand 9 contained in it, all of theseparts being of any approved construction. A cleaning gate 10 is formedin the sand of thetop box, and a passage 12 is formed under the cleaninggate, in the sand of the lower box, which connects'the cleaning gatewith the mold or metal space 2. A lateral passage 14 is formed in thesand of the top box which connects the pouring gate with the cleaninggate.

An upper strainer disk 15 and a lower strainer disk 18 are arranged inthe passage 12 under the cleaning gate, and the upper disk rests on thelower disk and has a concave recess 16 in its underside` and notches 17at its edges. The lower disk 18 has perforations 19.

The metal which is run into the pouring gate flows through the passage14 onto the top disk. The impurities are separated from the metal by theaction of the two disks, vand the impurities rise upwardly in thecleaning gate, while the clean metal passes through the notches andperforations of the two disks into the mold.

The notches of the upper disk are out of line with the perforations ofthe lower disk, so that when the metal flows through the perforations itdoes not draw down .impurities with it, as it would do if the upper diskwere not provided.

What I claim is:

1. In a mold, the combination, with mold ing material having a passageleading into the metal space, and having a cleaning gate and a pouringgate operatively connected together and with the said passage; of twostrainer disks arranged one above the other in the said passage andprovided with openings for the metal arranged out of line with eachother.

2. In a mold, the combination` with molding material having a passageleading into the metal space, and having a cleaning gate and a pouringgate operatively connected together and with the said passage; of anupper strainer disk and a lower strainer disk arranged in the saidpassage. the said upper disk having notches at its edges and a concaverecess in its underside, and the said lower disk having perforationsarranged o-ut of line with the notches of the upper disk.

3. In a mold, the combination. with a top bOX, and molding materialcontained therein and provided with a pouring gate, a cleaning gate` anda passage connecting the said gates; of a lower box. and moldingmaterial contained therein and provided with a passage which connectsthe said gates with the metal space of the mold; and two strainer disksarranged one above the other in the last said passage and verticallyunder the said cleaning gate.

In testimony whereof I have atliXed my signature in the presence of twowitnesses. GEORGE PETER KLINE.
